In the attached patch, I've implemented the DIRED-UP-DIRECTORY command
for Edwin, and bound it to #\^ as found in that other Emacs.
Please let me know if there's a better way of specifying "the next
directory up" than just merging the current directory with "..". I
read through the manual section on pathnames and the runtime pathname
code but I might have missed it.
Probably something like:
(merge-pathnames (make-pathname #f #f '(RELATIVE UP) #f #f #f)
(directory-pathname (dired-current-pathname)))
